How exactly do you push the dumbell down with your head when in the seated db extension position? Are these performed one arm at a time? I use the 100s and i cant lower it enough to push down with my head. I must be doing these wrong.
I use the 75s and can push down with my head but I feel an extreme pull on my shoulder
I wanted to know if I when I fail at holding for 60 seconds on a stretch if it would be wise to stretch for the time I missed or start over to hit 60. Or is it not recommended?
Is it ok for me to add ab work to this routine? I was planning on doing p90X ab ripper two days a week on off days
